Leners Patent No. 95,898, dared october 19, 1869.

IMPROVUILNT IN RULERS.

l The Sche'1 de referred to in these Letters Patent and making part of the same.

I, JOSEPH D. HALL, of the city of Trenton, county of Mercer, and State of New Jersey, have invented an Improvement in Rulers, to be known and designated as the Blotting-Pad Ruler, of which the following'is a specification.

My invention relates to the` combination of the -rlllerand blotting-pad,`iu such a manner as to render it impossible for the ink, or other liquid used for rulingpurposes, to come in contact with the paper or substance ruled or written upon, except as it is done through the nib or point of the writing or ruling-pen, the blotting-pad at all times presenting a surface between the ruler and the thing ruled, the frame being extended on either side beyond the lower edge of the ruler, and intercepting any ink which might otherwise iow from the edge of the ruler to the paper to be ruled.

The fi'ame which holds the blotting-pad is attached to the ruler by a hinge and pins, as shown in the accompanying drawing. I do not limit myself to this nor any particular manner of attaching the frame. It mav be donev by pins or clasps, attached to each end of the ruler and 'ame, or by a hinge and clasp, or iu such other way as may he most desirable and convenient. The blotting-pad is folded around the flame, and the edges fastened wit-l1 Inucilage. It can be slipped om the frame and changed at pleasure. This permits the use of eitherside of the blotting-pad, but it is not necessary that it should be fastened at the edges, as the-frame, when the ruler is closed upon it, will be sucient to hold the blotting-pad in position.

Description of the Accompanying Drawings.

Figure 3 shows one edge of the ruler.

Figure 5, the end of the blotting-pad and frame.

I disclaim all rulers having but one roller and blotter attached, and which is to actas ruler, blotter, and paper-cutter,

I also disclaim the combination known as the combination of blotter, paper-weight, rule, cutter, and square. A

I also disclaim, the .improvement in blotting-pad, all'these having been heretofore known and used.

I claim, as my inveutioni The combination, of the ruler and blottingpad with the frame which holds the blotting-pad, and the manner of attaching them, substantially as described, and for the purposes hereinbefore set forth.
